[ANSWERED] Modifying an already existing AIO ISO

I have an AIO iso that i am currently using, and want to modify it for OEM Info/Backgrounds, slipstream 452 etc. How can i do this. Anytime i mount the iso, i have to select a version of Win 7.

A WIM file can agregate various windows versions, called images. WinReducer works with ONE image at a time. So, you have to do the modifications you want in each image separately.

A note: don't check "remove uneeded editions" or you will loose the other images!

Another question similar to above:
I have a Windows 7 ISO with integrated updates, I don't know what method used for integrating updates to it.
What latest WinReducer has ability to work on this ISO? Last time I was unable to work on these ISOs of Windows 7 and 8.1.
         OR
There is any method to extract integrated updates from the Windows ISO and use them later after customizing?

Try Winrar or 7zip to extract the iso file to a folder.

I was using WinToolKit looks like the main site is down and the software unusable also I hope they fix it soon.....
